Summary

The most common conventional approach towards the analysis of ultrasound data is the formation of an image from the envelope of the received signals. In so doing, any information which may be encoded in the phase of the signals is disregarded. More recently, applications such as tissue characterisation and doppler techniques have begun to make indirect use of this additional information, but its full potential remains unrealised.

In this paper we illustrate how phase can be used to provide vital information, of benefit in tissue characterisation and also concerning image artefacts, such as speckle, leading to novel techniques for speckle reduction which can realistically be implemented in real-time data analysis. We also show how these techniques can be extended to include the processing of doppler data and images.
